Samuel R. Walker advertised Quitman’s filibustering expedition against Spanish Cuba by appeals to patriotism, to religion, to the missionary spirit of the American people, and to their wish for domestic tranquility in a healthy Union. He came around at last to another hallowed American folkway: making money. Taking Cuba would surely enrich the filibusters. The Cuban Junta promised Quitman millions and a plantation. The invaders would surely find a few propertied loyalists to dispossess and share that booty amongst themselves. But even for those who did not go or invest in the effort themselves, profits beckoned.
Look at it as a commercial question, and the necessity of a change in the political condition of the Island of Cuba appeals with an irresistible power to the mercantile mind of this country, and to that of the commercial world. See how our commerce is harassed by an island so governed, guarding the mouth of the mightiest river in the world, whose shores are bordered by the rich States of the West, and bearing on its bosom their untold wealth-this land governed by a jealous, unfriendly, and pusillanimous power, whose only aim seems to be, to embarrass all intercourse with us-tampering with our national honor, just so far as they may believe their weakness will be their protection-vaunting with the boldness of a braggart, and trembling with the trepidation of a coward-driving, by high and excessive duties, all our products from her markets, when the articles we produce are those they most need-our citizens are insulted even as the Creoles themselves! How long would England or France endure a condition of things like this? How long would they have suffered such an incubus to have existed at the outlet of even their petty rivers, weighing down their commercial advancement, and not have removed the cause?
Walker knew how to play his audience, most especially commercially minded and filibuster friendly New Orleans merchants. But even when appealing to their self-interest he takes care to dress it up in patriotic language. The Spanish insulted the national honor by interfering with the shipping routes. The British and French would not stand for such insulting customs shenanigans. Patriotism and profit ran close together.
Taking Cuba would remove all those burdens to trade. But if sweet reason and a handy carrot could not woo supporters unaided, Walker had a stick too:
Let Cuba be Africanized, and then with another San Domingo [Haiti] blocking the mouth of the Mississippi, all we can do by internal improvements will help us little. Our seas will be divested of ships, and those white-winged birds of commerce will fly to other oceans, or furl their pinions, and droop upon our waters.
Accepting the status quo did not mean getting more of the status quo in return. Who knew what the Spanish would do next, with the British and French plotting (1, 2, 3, 4) with them? They might go ahead with their terrifying program to free the slaves anyway, and turn the present state of uncertainty and harassment into a far more active campaign of obstructing trade. Inaction might mean not just accepting the present circumstances, but rather inviting far worse calamities. Americans must wake up. They had profits to lose as well as to gain. By taking Cuba, they could eliminate the risk of loss and ensure the gains.
